" CHARLES T. BRADY, onDErRoInMIcHIGAn f LAMP siinnn Application filedNovember 19, 1928. Y-Sferl'allho.i 320,309.

In my co-pending application, S'erial No. 312,423, 4iiled October 15,1928', I have disclosed a lampshade equipped to produce a filtered lightresembling daylight; This l 5 function. is accomplished by aclosure mem#ber in the light-emitting end of the shade and a suitablelens in theclosure member.

i. In replacing the lamp Within the shade, it

is found desirable to .remove the closure vention is to provide aconstruction wherein this member is readily removable.

` The invention is fully disclosed by vway of example in the followingdescription and in the accompanying drawing, in whichy Figure 1 is aperspective View of the lamp i shade with the `closure member removedtherefrom ,f

device, with the closure member in place in the lamp shade.

ployed to designate corresponding parts throughout. x A The lamp shadeis builtfon a wire frame of more or less conventional construction,

`shaped ribs 3. The word rings asused is passed to the lamp within theshade. In

ner ring 6 preferably of somewhat smaller dimensions than the ring landserving purpose whichA will presently be described.A g The frame'consisting ofthe rings land 2` and the ribs `3 is covered withanysuitablej material 'T suchas parchment or silk.

As already stated, the Vlightissuing frornq` the lamp within the shadeis iiltered, and it is therefore necessary to obstruct the light thefilter. In accordance with these condithe rods 10 and secured thereto. nFig. 2 is `a perspective viewof the closure i member apart from the lampshade; and

` Fig. 3 is a vertical section of the complete` including at leastonelower ring 1 and an; upper ring 2 defining the ends of the frame.Vwhich are joined by suitably spaced and` the lower endof the frame issecured an innexcept where is is permitted to pass through i tionsVthere is `provided aA closure member` adapted to tit into the`lighteemitting end" of the shade. i. This member consists of a` sheetSoi substantially opaque material having its edge wound on la ring 9`havinO' a f ,configuration similar to the` ring 6..` he ring 9 is of asize very approximatetothat of the ring 6' so that itwill not passloosely through the ring 6 but only whenboth rings] aresomewhatdistorted. Inasmuch fasthe rings are Vof a resilient material, `Jtheypromptly` resume their original configura# i tion, whereupon the ringlsupports the ring 9 and `does not permit it to fall therethrough,` asclearly shown in `Figure 3. n n *A air ,of rods :10 are securedacrossthe ring 9,V and shorter rods 11;are` laid across In the 4material'8 isicut an opening 12 coincident n n with theyrectangle formed bythei"odsllO i0 4'and 11, andthe material at the edges fof `this `openin g`is wound on the rods as indicated `by' the numeral 13'.` One oithetransverse jReerence to these views will now be made by use of likecharacters which are emrods 11 carries` a pair of lugs 14 in which `isjourna-led a hingefrod "15.` `'lhejopening 1Q U'ff is covered "by ashutter 16"lravinga` pair o "lugs 17 lying adjacentthe lugs 14 and lalsopenetrated by'therod 15." Coil springs 18 surroundthe rod 15, with oneendh'fixed.. thereto andthe other-end engaging the undersideothe shutter16" whereby the latter is normallyheld up against the lowerface `of theclosure member. l i y, 1 y The shutter inzturn has a central opening` d20 in which is mounted a condensinglens 21.

On the incident or flat side of the lens is laid a light filter" 22heldin positionf by means of clips 23 and consisting preferablyof Va`fiat dish ofglass of bluish tint. C

Across therodslO, at the inner side of the `closure member, is supporteda yoke 25H having` a loop 26` inthe 'bacljthereof Behindtlie yoke isstill another transverse rodQfi` having n rfalso a .loop 28 lyingsubstantially"parallel to o5 H theplane `ofthe material `8` as clearlyshown in. Fsureeid i The i QGSLipiOit a lamp socket 29 which in turnreceives a lamp 30, VVThe loop"28 supports' a screwfswitch 31 having itsterminalsjoined to the line 32 andl "-00 to the lamp socket 29 in anyconventional manner.

Inasmuch as the rings G and 9 are of spring Wire, as already indicated,they may be distorted in such a manner as to permit the closure memberto be separated from the lamp shade in order to permit access to thelamp 30 in the socket 29. After the lamp has been rereplaced, theclosure member is restored to the position shown in Figure 3 in likemanner, as already stated.

Although a specific embodiment of the invention has been illustrated anddescribed, Vit will be understood that various alterations in thedetails of construction may be made Without departing from the scope ofthe invention, as indicated by the appended claims.

What I claim is l. In combination with a lamp shade including acontinuous ring member of spring mate-rial at the light-emitting endthereof, a closure member consistingl of a frame member of springmaterial and of substantially the same dimensions as said ring member,said frame member being adapted to pass through said ring member and tobe supported thereby, a substantially opaque material covering said lastnamed frame member, and a light-modifying device inserted in saidmaterial.

2. In combination with a lamp shade including a ring member of springmaterial at the light-emitting end thereof, a closure member consistingof a frame member oi spring material and of substantially the samedimensions as said ring member, a substantially opaque material coveringsaid last named frame member, said material having an opening, a shutterhinged to the closure member and adapted to cover said opening, and alight-modifying device in said shutter.

In combination with a lamp shade including a ring member of spring`material at the light-emitting end thereof, a closure member consistingof a frame member of spring material and of substantially the samedimensions as said ring member, a substair tially opaque materialcovering said last named frame member, said material having an opening,rods laid across said last named frame member, a shutter hingedlysupported by said rods and adapted to cover said opening, and alight-modifying device in said shutter.

4. A lamp shade comprising a covered wire frame, a supporting ringcarried by said trame in the light-emitting end thereof,

another ring adapted to be detachably sup- 1 ported by the first namedring, and a lens carried by the second named ring, said irst named ringbeing set inwardly of the 'lightemitting end in the axial direction ofsaid frame, whereby saidlens is concealed in said end.
